etckeeper is a collection of tools to let
/etc be stored in a git, mercurial, darcs, or bzr repository. It hooks into
apt (and other package managers including
pacman-g2) to automatically commit changes made to
/etc during package upgrades. It tracks file metadata that revison control systems do not normally support, but that is important for
/etc, such as the permissions of
/etc/shadow. It is quite modular and configurable, while also being simple to use if you understand the basics of working with revision control.
